    This table contains data from 1972 to 1977 for the upper gradient bridge of
    Apollo 17 probe 2 in this bundle's 'split' format. It includes data from
    PDS3 product A17A-L-HFE-3-THERMAL-CONDUCTIVITY-V1.0:A17_HFE_P2_1-201201,
    PDS4 product
    urn:nasa:pds:a17hfe_calibrated_arcsav:data:a17_hfe_1975_l2_arcsav_tg21, and
    data released by Nagihara et al. along with the article "Examination of the
    Long‐Term Subsurface Warming Observed at the Apollo 15 and 17 Sites
    Utilizing the Newly Restored Heat Flow Experiment Data From 1975 to 1977,"
